Title: Color cathode ray tube
Inventor: YAMAJKI HIDEDOSI
IPC: H01J29/07
Filed: 1985-10-11
Granted: 1990-05-03
Abstract: The structure comprises a shadow mask which has a main surface having a number of apertures and a skirt portion bent away from the surface.  A frame supporting the skirt of the shadow mask is formed of a metal having a greater coefficient of thermal expansion than that of the shadow mask.  The shadow mask is welded to the frame at a number of points.  The structure is such that the skirt is subject to an inward compressive stress from the frame.  The shadow mask structure is preferably rectangular and the skirt is such as to produce an elastic deformation of 2mm at maximum.  The shadow mask may be of iron-nickel alloy and the frame of iron.

Abstract: A knife (1) comprises a rectangular body member (2) and a blade member (4) which has a blade (4a) and hinged at the one end (2a) of the body member through a supporting shaft (3).  The blade is turnable to A direction and can be stretched out to be straight to the body member for using as knife.  The blade member can use as scissors when the blade is stretched out to be acute angle with the body.  An elastic member (6) is formed along the back side of the body so that when the cutting member is pushed, the edge part (6b) of the elastic member is turnable to meet elasticity.  When the blade is not to be used, the edge part can be elastically deformed to the perpendicular direction of the turning blade.

Abstract: The memory circuit includes a chip history storing means (HR) such that users  classify  the  products  and  grasp  the  use  of product. The memory circuit comprises a memory cell array (MVA), a means for buffering address  signal,  a  means  for  decoding  the address signal, the chip history storing  means  for  storing  the history of chip and including  extra  memory  cell  array,  and  a driving means (HRD) for driving the  chip  history  storing  means (HR) to input or output the chip history data to a from  the  chip history storing means (HR). A word line of the decoding means  and the extra memory cell array owns a bit line jointly.

Title: Method for making ginseng tea
Inventor: SO KI-BONG
IPC: A23F3/34
Filed: 1990-12-18
Granted: 1993-07-21
Abstract: The ginseng tea having coffee taste is  prepd.  by  (a)  roasting each  of by-product ginseng or ginseng extract (I),bean (II) and barley (iii) respectively at 200-551 deg.C, 150-250 deg.C and 150-230 deg.C, pulverizing, and extracting with hot water, (b) concerntrating the each extract of (I), (II) and (III) at 70-80 deg.C and 600-700 mmHg, and (c) mixing the concentrated (I), (II) and (III) to obtain the final procuct. Ther mixing ratio of (I):(II):(III) is 10-15:2-4:1-3.

Title: Sense control method and circuit of master type
Inventor: YUN SANG-HUI
IPC: G06F13/14
Filed: 1990-12-24
Granted: 1992-10-16
Abstract: The method is for integrating  watching  controls  of  hybrid multiplexer system operating with self units into  the  integrated system operating with rack-units by connecting  all  selves  to  a wire. The method can also vary the setting  of  master  slave  and transmit the Tx/Rx data without interruption through a  wire.  The circuit is composed of central  processing  units  (CPU1-CPUn)  of self units connected to a wire for watching control expansion (21) and a terminal (TA) connected to one  of  the  central  processing units (CPU1-CPUn).

Title: Drum washer
Inventor: KWON HO-CHOL
IPC: D06F23/02
Filed: 1990-12-27
Granted: 1992-11-27
Abstract: The washing machine comprises a roller lift (21) for  rubbing the laundry in the opposite direction against the drum (1), a lift cover (2) for proventing the laundry winding on  the  roller  lift (2), a driving means for rotating the  lift  roller.  The  washing machine includes a lift damper (24) connected to  the  lift  cover (22), lift shaft (23) formed integrally with the  damper,  a  lift pulley (26) fixed to the lift shaft, a middle  gear  (27)  mounted between drum pulley (8) and lift pulley (26), and can  rotate  the roller lift (21) in the opposite direction to the lift pulley (26) when the drum pulley rotates.
